WILLIAM A. GREEK AND DARIUS L. TURNER, OF'COALINGA, CALIFORNIA.

- To' all whom 1' i may concern:

' Be it known that We,.lVILLIAM A. Gmzsn and Dames L. TURNER, citizens of the United States, residing at Coalinga in the 5 county of Fresno and State of California,

. have invented new and useful Improvements in Calf-Wheels for Oil-Wells, of

which the following is 'a specification.

The invention relates to calf wheels for to water or oil wells.

The primary object of the invention is the provision of a wheel in which the hub thereof is constructed from metal, the spokes and rim being constructed from wood and are gether, whereby the same may be easily and readilv. assembled by an inexperienced workman, and also disassembled,' so that. the necessary repairs may be made to such wheel, should the occasion require.

Anotier ol"ect of the invention is the provision of a wheel structure that will be non-clcstructible. and that may be subjected to the maximum amount of wear, without injuring or weakening the se ne. and that may be set up or taken apart when desired A further object of'the. invention is the provision of a. wheel of this character which is simple in construction, strong, durable. re- 39 liable and ellicient in operation, and inexpensive in manufacture. With these and other objects in view, the invention consists in the construction, comibination and arrangement of parts, as will trated in the accompanying drawings. and pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a fragmentary side elevation of a f ame rigging show- 40 ing the wheel constructed in accordance with the invention mounted therein. Fig. 2 is a front elevation thereof. Fig. 3 is an enlarged fragmentary side elevation of the wheel. Fig. 4 is an enlarged vertical longi- 46 tudinal sectional view through the wheel and the drum.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

50 Referring to the drawings by numerals, 10 designates a. frame rigging which is of the ordinary well-known construction, for use in boring or drilling water or oil wells, and includes standards 11, to which are suitably bolted split aiming bearings in which is journaled e. supporting shaft. 13,l

CALIF-WHEEL FOR OIL-WELLS.

Specification of Letters Patent.

Application filed December 10, 1910. Serial No. 596,610.

periphery of the disk 15 and formed integral therewith is an octagonal-shaped bearing flange 18. the same projecting from the outer face of the said disk and is connected with the boss 14 by means of radially extending webs l9 integral therewith and with. the disk and the said flange for materially strengthening the latter. Connected with the flange 18 is a plurality of outwardl v projecting spokes or arms 20. the inner end of each being: beveled and abutting against the adjacent arm or spoke. Thes spokes or arms 20 are secured to the, flange by ueans of a plurality of bolt members 21 which are passed through the said arms or spokes i) and the flange 18 on the hub, thus it will be seen than any one of the said spokes or arms 20 may be detached from the hub, should the occas on require, without disturbing the other spoke or arm. thereby enabling the wheel to be repaired when the same has been damaged by the breaking thereof or otherwise.

It is evident that each arm or spoke 20 when secured to the flange 18 of the hub PIOJClS at an acute angle with respect to the adjacent spoke or arm and secured to the outer end of The said arm or spoke 20 is an annular rim 22 which is preferably constructed from wood, the same being secured to the spokes by means of bolt mem: here 23. whereby it'may be readily and easili, detached at will; This rim 22 is mounted at the outer ends of the spokes or arms 20 against the outer side edges thereof. Engaged by the bolt members 23 and se- 1 cured against the opposite or inner side edges of the spokes or arms 20 at their outer endis a. sprocket wheel 24, over which is trained a drivcn'sprocketchain (not shown) which is driven i'gom a band wheel shaft, the no being also not shown, as it is 01' the ordinary well-known construction.

' formed with an annular outt-urned flange $7, the same snugly fitted within a correspondingly-shaped counter seat 28 formed in the inner face of the disk of the hub, the flange 27 being secured to the disk 15 by means ot'tap bolts 29 passed through the latter and the said flange, thus securing the drum to the hub of the calf wheel. At

' the opposite end of the cylindrical body 25 is arranged a circular guide head comprising a disk 30, the same being formed with an outwardly extending central boss 31, from which radiate at intervals brace webs 32 which are integral with the'boss 31 and disk 30 for strengthening the same Formed on the. inner face of the disk 30 concentrically with respect to the arms 20 is w thin the end otthe cylindrical body 25.

' the body being connected to the disk 30 by means of tap bolts 3i which are passed through the disk 30 and engage in the body 25. The boss 31 of the guide head is formed with a suitable central opening for receiving the shaft 13- and threaded in the said boss is a binding or set screw 35 which 1 whereby the same will abut with each other ,at their inner ends, av rim detachably conncctcd to the free ends of the spokes, and

engages the shaft 13 for locking the guide disk thereto.

Provided in the disk 30 of the guide head is an opening 36 which is contiguous one of the brace webs 32 and through this apertare 36 is passed one end of a rope or cable 7 37 which is adapted to be wound or unwound upon the cylindrical body 25 forming the drum. The end of the cable 37 passed through the opening 36 is clamps by means of a hook-like bolt member 38 which is engaged in the brace web 32 adjacent the aperture 36 in the disk 30 of the guide head, and in this manner the cable or rope 37 is held secured thereto for the windsame onto and ing and unwinding of the from the drum.

Overlyin the inner ends of the spokes 20 against their outer faces beneath the heads of the-bolt members 21 are bearing plates 39, thus preventing the said heads of the bolt members from cutting into the spokes when such members have been tightened. the plates 30 being of a size to receive all of the bolt members 21 that go through the spokes 20 for connecting the same to the hub of the wheel.

What is claimed is: The combination with a hollow cylindrical drum having an outturned annular flange at one end thereof, of a hub comprising a circular-shaped disk formed with a (:5

central boss projecting from the outer face thereof. an octagonal shaped flange formed integral with and projecting from the outer face of the said disk, circumferentiallywith an annular shoulder 33 which snugly fits respect to the said boss, radial webs joining the boss'with the flange, the said disk being provided with a recess on its inner face for receiving the outturned flange on the drum,

screw members passed through the disk and the outturned flange on the drum for connecting the same, spokes detachably connected to the octagonal shaped flange, the inner ends of the spokes being beveled,

a guide head detachably connected to the opposite end of the drum.

In testimony whereof we atfix our signatures in presence oftwo witnesses.
